Makro Alberton RCS Group *****

On Thursday, 22/08/19 i received messages saying "Thank you for purchasing at Foschini retail on card***** for R..........(amount) on 22/08/19 at 19:41. After that i received another message saying the same but for a different amount. This was at 19:44. And then a message saying PLEASE NOTE THAT THE BALANCE ON YOUR MAKRO CARD IS NOW MORE THAN YOUR CREDIT LIMIT AND THIS ADDITIONAL AMOUNT WILL BE ADDED TO YOUR NEXT INSTALMENT" I contacted the customer line and asked them to stop the card. I would LOVE to know how can someone use my Makro credit card without my Makro card, My Makro credit card,My id, the sms that is sent to ones phone, and also after hours when the place is closed?? And how does someone "buy" something from Foshini retail at Makro. This sound like an inside job to me from the people at RCS group. Don't you think?
